BLDC Motor Driver Unit (STM32)

This BLDC Driver is a driving unit specifically designed for Brushless DC Motors (BLDC), using an STM32 as the primary control chip. It provides precise control over the DRV11873PWPR motor drive chip through I2C communication, facilitating PWM speed control adjustment, monitoring, and direction-switching. This drive chip features a control interface and integrated stall protection, which leads to efficient and low-noise operation of three-phase small brushless DC motors. The onboard STM32 upgrade interface provides firmware updates and functional expansions, making it useful for projects involving industrial automation, smart robotics, precision instruments, and other fields.
